If you’re developing on ‘something fairly recent’, you shouldn’t see any difference except it would be a wise time to wipe your build dirs and re-CMake from clean. If you’re on a ‘somewhat older’ Linux, the baselines being Ubuntu 18.04 (their previous LTS) and CentOS 7 (which our Jenkins runs), you should also be fine except for GCC, where you will need a version supporting C++14: in practice this means GCC 5.x or higher. (Or use Clang…) For both of these distros there are officially supported ways to get newer GCCs (we’re actually using GCC 9 on Jenkins now..), so I don’t expect this to be a problem. | If you’re developing on ‘something fairly recent’, you shouldn’t see any difference except it would be a wise time to wipe your build dirs and re-CMake from clean.

As part of this we now require CMake 3.10, Qt 5.9 and OSG 3.4.1, and James started removing various legacy pieces from next around this. There are plenty more cleanups that can be done based on this : especially on the CMake and C++ sides. Things like Boost -> Std stuff, Cmake targets-as-objects support (eg, target_compile_features can be used now). | As part of this we now require CMake 3.10<ref>https://sourceforge.net/p/flightgear/mailman/message/37094732/</ref>, Qt 5.9 and OSG 3.4.1, and James started removing various legacy pieces from next around this.

Windows and macOS should be unaffected BTW - because on those platforms you're always running something you downloaded which is fairly up to date. If you choose to go and download an ancient version of CMake or Qt, on either platform that’s your problem to fix - but you’ll get a configuration error at least. | Windows and macOS should be unaffected BTW - because on those platforms you're always running something you downloaded which is fairly up to date.
